Temchit's apartment on the 24th floor of a high rise building next to the university campus on Asoke Montri, Sukhumwit is a great place to stay. It has 2 rooms separated by a sliding glass door, a kitchen and a bathroom. It is clean, quiet, tastefully decorated and offers a pleasant ambience suitable for a longer term stay. The large double bed is very comfortable. The kitchen has 2 hotplates with a microwave oven and a large fridge and freezer combination, so cooking is definitely possible. The building has a carpark.
I have stayed in this area of Sukhumwit many times and have witnessed its development over the years. Now there are many upmarket restaurants and food outlets within easy reach but also more basic restaurants and streetfood stalls. Most of the restaurants are Thai, Japanese and Korean, with occasional European restaurants sprinkled around the area. Twice a week there is a market on the university grounds.
The building is situated within walking distance of Petchaburi underground station and Makasan Airport Link, so it is very convenient for travel around Bangkok and to and from the airport. In the opposite direction Terminal 21 shopping centre and the Skytrain at the Asoke junction are about 12 minutes away on foot. There is also river transportation nearby at Asoke Pier. There are several 7 11 convenience stores in the immediate vicinity.
Asoke Montri Road is very busy and loud, but the apartment building is set back from the road and is thus very quiet. It has a fairly large roof swimming pool which is fairly well kept.
I would highly recommend this reasonably-priced condo for 1 - 3 people.
